Along the lines of the (sadly defunct) Regretsy, Worst Things for Sale, Kickfailure, Comics Curmudgeon, etc.
Preferably something single-target focused versus sites like Cracked which may make fun of five dumb video games but aren’t really a site dedicated to making fun of dumb video games.
There’s a facebook page called Food Babe which has a lot of, um, not really woo, but let’s just call it over the top advice since I really only looked at the page once so I don’t know a whole lot about it.
The reason I saw it was because of a page called The Food Hunk which was only created to lampoon it.
Here’s a blog mocking the comic For Better Or For Worse.
you can’t go wrong with the classic cakewrecks the cakes are funny but the commentary is even better
one of my favorites here
My long-time favourite is the Gallery of Regrettable Food … the Guide to Meat Fisting At Home just *kills *me. So to speak.
Then there’s MOBA - the Museum of Bad Art.
Thanks for the suggestions, all.
Adding to my own list (to share with you and in case anyone else was going to recommend it): Stupid Comics.
When I was brand-new to the internet, I used to lurk at a site called Catty Goths, where “genuine” (licensed and certified?) goth girls and boys would post the personal websites of lame loser goths to make fun of them.
It was actually pretty entertaining.
The site’s long gone but…if anyone knows of any equally ridiculous goth-on-goth shaming blogs, drop a link here, please!
that actually sounds mean. 
does anyone know of that site where bad photos from real estate ads are posted? I’ve been there but darned if I can find it.
Well, what I got a kick out of was the fact that EVERYONE involved was lame: the people being made fun of, the people making the fun, and me for being entertained by it all. 
There’s Catalog Living, which attempts to help us glimpse the mental workings of the people whose houses you see in catalogs.
And Literally Unbelievable, documenting people who believe Onion stories are real.

Really bad taxidermy.
Or crappy taxidermy, if you prefer.
thanks, I find those hysterical
